A year after graduating from Harvard in 2011 and moving to Walla Walla, Gabriel began managing the family owned estate winery, Garrison Creek Cellars, which produces limited quantities of single vineyard red wines from Les Collines. After a succesful five-year span overseeing the winery, he has now transitioned to a wider supervisory role, focusing on the recently expanded operations of Les Collines Vineyard after the Murr family acquired sole ownership in 2018.
